If the dot clock is low enough ( NOT in this case for my board ) you can put the entry even in the 16bpp and 32bpp sec- tions. .:: spice-jitterbug-1ea.notion.site ::. .:: edabit.com ::.

The /etc/Xaccel.ini will look something like this

You can check your conversion by running the vgaset program with no parameters while running the Xinside server: it will output an XFree-like line and, if everything went OK, this line will be equal to the line you started from ( except if b and c are equal, I haven't been able to reproduce this situation in Xinside: the best case was c=b+1 ).
